Clipping Rates are determined based on an item’s parameters, allowing a hierarchy of rates to be applied, instead of a single rate that applies at the highest level of the rate lookup structure.

The purpose behind Clipped Rates is to calculate a shipment charge that is based on a tier of individually-calculated rates that are then added up to arrive at the total charge. The difference between a Clipped and a Non-Clipped Rate is that the Clipped Rate is calculated from the lowest level of the Rate Lookup structure that is defined, and for ALL subsequent “level breaks”, up to and including the level that encompasses the total n of the shipment, where n could be weight, height, length, volume, girth, etc. The calculation for a Non-Clipped Rate is made only at the level that includes the total n of the shipment, ignoring the lower levels completely.
